fl'ri all whom it may con/cern.-

- Be it known that I, VTHOMAS LnoNAmn n. .citizen of the United States, residing et State of Illinois, have invented e new and useful Grainar Door, of which the followf ing is a specification.

1 This invention-relates to the supplemental r linside guard doors employed in eers for l1o Crrying grain and like products or materiel, Y and has forfits object to ini Drovel the con- "I struction ond increase thee iciency of devices of this character. With. these and other objects in view which will appear es thennture of the invention is better understood, the invention vconsists in certain novel features et. construction es hereafter fully described and claimed, In the accompanying drawings forming e 2,01- port ofk this speciicetion and ir which correspending parts are denoted iig-like designetm /ng' characters, 'is illustrated the preferred form of the embodiinentol the"invention'eezgferatioln. 5, In",he-d1owings, vfigure l, isn sectional elevation of o portion ein greinnr/ viewed from the inside, including one l' the doorwey openings, with the improved-grain door etdied. Fia. 2 is `e section on the line 2--2 gfotFi .1. lig.' 3 is a' sectional detziiL-*enm large on the line 3--3 of Fig. 1; i

1n the improved device is comprised o grain door in two sections, an upper section andre. lower section 11, ol substantially 'equal size and hinged together et 12, to deiect inwardly' or toward the interior ol' the car, .i The door sections ore constructed with sheet metal bodies ]0`-1l, preferably ol' ,steel, with strengthening lraines around the ',gdges, the frames being oiE L shaped bers with theouter Het feces ol' the l'rinne meinbers at the hinged edges bearing' against ench other and firmly supporting the 'sections mid "bucklef' or bend outwardly under the stieins imparted thereto by the groin from withinthe car. The hinges 12 are construct- "ed with their pintles disposed at e consider'` able distance from the adjacent or outer faces of the door sections, to still. .further brace and support the saine from outward deflection.

The outwardpressure of thegrain when Champaign, in thecounty of Champaign and piible of carrying the seine`intdprectical op' preventing any tendency ol the sinne to` the eer is loaded isconstimt :md severe, hence the importance ol zi door .so constructn ed es to present :L corrospondinpjly .strong resistance to such pressure, ll`he device herein shown amd described ellectuzilly resists this outward press-u ro, :is will he obvious.

The lower door section I l is l'ormod with on opening 12% iu the lower portion and the opening; closed by simili doors lll-l5 hinged :it low-i7 to the door section sind with one door ovorlupping the other :it their meeting edges, so that one parir oly bolts or catches 18 may he employed to hold both doors in. closed position, the witches boing' preferably operative sinnillnneously by n lover .I9 ond rods 20v-2 l.

The snmiler doors provide moons for the discharge oll the groin without opening the larger doors, or lor discharging; the portion ol the lood which comes opposite the larger doorway, in thil usuel nimmer. The upper door soci iony l l is also provided with :in opening 122, closed by slidingr doors ffies-24. operetingin guides 2.13 Z6 on the mein door section l ll), the doors held closed by e hook 27, and

Supported by spared lui-rigors 2S) within the cor :nid ubove the door-ny opening, is e truck Ii() preferably in the l'orni ol' n, circuler rod, :ind attached to the upper door section are brackets Iyl W32 havingr rollers Iii #34 boeriner upon the tritt-h. By this moons the hinged door sections nre .supported in position lo be moved longitudinally ol the cer, when not required.

Vl'hon the improved door is to be removed from the roer ol' the mitin loorwey opening, it is buckled inwardly :is indicated by dotted lines in Fig. il, und swung.upwardly toward the eer roof upon the tinck $5() irs o, hinge` and the lower section ll loldod heneiith the upper section, or between it :ind the adjacent sido ol the ein, ond \\'hen .the loldod door sections lieve been moved iilong the track for enough to clean' the ironie oll the doorway, theyr :iro lowered in 'olded positions into the spnco within the .l'rinning ol` the cer between the doorwey opening` :md the ond ol the cer. When thus disposed tlul sections remain 'firmly in position end zn'ehold by gravity only, end require no histenings or catches to retain thein 1n piece.

The track 30 is provided with depressions 35 where the wheels 3.3,34 come when the section having anopening at the respective upper and' lower edges thereof and angle irons extending Ironi said openings to the meeting edges of the sections, doors arranged to close said openings, a track supported above the doorway and extending beyond the side thereof, and hangers bearing Inovahly upon v'said track.

In testimony that I olaiin the foregoing as my own, I have hereto aliiXed iny signature in the presence oi two Witnesses. v
